Pulping digestion agent production method

Abstract

The invention is a producing method of paper pulp boiling agent, its raw materials comprising penetrating agent BS 4-10 weight shares, sodium bisulfate 4-10 weight shares, sodium chloride 4-10 weight shares, pleregal 0 15-25 weight shares, polyoxyethylenated alcohol 15-25 weight shares, alkyl sulphonate 40-55 weight shares, and water 60-80 weight shares. The producing process: adding the pleregal 0 and polyoxyethylenated alcohol in the 55-65 deg.C water, heating to 70-75deg.C, blending, and adding in alkyl sulphonate, blending and adding in BS, sodium bisulfate, sodium chloride, blending, cooling to 30-40deg.C, and blending to make the finished product.

Description

Technical field:

[0001] The invention relates to an auxiliary agent in the papermaking industry, that is, a production method of a cooking agent for making paper pulp. Background technique:

[0002] At present, the auxiliary agents used by domestic papermaking enterprises for cooking and pulping are usually alkali sulfide, anthraquinone and anthraquinone derivatives, which are all auxiliary agents that cause serious pollution to the environment, especially anthraquinone and its derivatives are Teratogenic pollutants. Contents of the invention

[0003] Aiming at the problem of environmental pollution caused by traditional auxiliary agents, the invention proposes a low-pollution production method of cooking agent for pulp making.

[0004] The production method of the cooking agent of this papermaking pulp, its characteristics are as follows:

[0005] 1. Raw material components:

[0006] ① Penetrant BS, liquid, specific gravity 1.02, weight 4-10 parts;

[0007] ②Sodium bi...
